High Quality Content by WIKIPEDIA articles! Gabardine is a tough, tightly woven fabric used to make suits, overcoats, trousers, uniforms, windbreakers, and other garments. The fibre used to make the fabric is traditionally worsted wool, but may also be cotton, texturized polyester, or a blend. Gabardine is woven as a warp-faced steep or regular twill, with a prominent diagonal rib on the face and smooth surface on the back. Garbardine always has many more warp than weft yarns.
